Hi people.
I'm working on some device automation application and need to connect to it via a serial pport and a RS232 interface and send and recieve ASCII data to the port. I've used some codes like this:

SerialPort srp = new SerialPort("COM2", 19200, Parity.None, 8, StopBits.One);

srp.Open();
srp.WriteLine("some commands");
srp.Close();

My device takes no action with this code but I'm sure about the command syntax. Is the problem in my used code? Could anyone help me please?

Hi,

When you use writeLine Method that writes the specified string and the NewLine value to the output buffer. The New line is maybe the problem. You can verify this.

Hi
Your code seems right?
You can download any virtual Serial port emulator . Pair any two virtual port and let your application connect with any port ,just paired. Send the message to the same port , you will can listen to other port using the Microsoft hyper terminal ( or you can create your own app to listen and send message to a port). If you are getting the message properly ,then there is no issues in your code . May be the delimiter is the issue.

hope this will help you.
I am usingvirtual serial port emulator from http://www.eterlogic.com/[^]

I am not an expert but have you tried this?

SerialPort srp = new SerialPort("COM2", 19200, Parity.None, 8, StopBits.One);
srp.Open();
srp.WriteLine("some commands"+Environment.NewLine);
srp.Close();
